Problems solved by technology

[0015] Therefore, in the above-mentioned inversion driving technique of the prior art liquid crystal display device, when the liquid crystal panel is driven with a predetermined inversion method (for example, one horizontal point and two vertical points, one horizontal point and one vertical point, etc.) to display an off pattern , horizontal crosstalk occurs due to the offset of the common voltage

Embodiment Construction

[0024] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0025] image 3 is a block diagram of one embodiment of an apparatus for controlling driving of a liquid crystal display device according to the present invention. As shown therein, the device includes: a timing controller for processing input RGB data by a specific inversion method to provide data to the data driver 33, and if the input of the RGB data for the off-pattern is checked As a result, it is judged that the RGB data of the off pattern is input, the RGB data is converted by an inversion driving method that does not cause crosstalk to provide the data; The pass signal control signal outputs the gate signal to each gate line GL1~GLn of the liquid crystal panel 34; the data driver 33 is used to respond to the data signal control signal provided from the timing controller 31 to each data line of the liquid crystal panel 34 The lines DL1˜DL...

Abstract

The invention provides a driving device and method for controlling liquid crystal display device. When the liquid crystal panel is driven by reversal process, the turn-off pattern is displayed and the reversal process is changed into another reversal process without vertical crosstalk. The driving device comprises: a timing controller for processing and inputting RGB data using special reversal process to provides data to a data driver and changing the RGB data to provides the data using the reversal driving process without crosstalk after inputting the RGB data of turn-off pattern; a strobe driver for outputting the strobe signal to each strobe line of liquid crystal panel in response to the strode signal control signal; and a data driver for providing data voltage to each data line of the liquid crystal panel in response to the digital signal control signal.

Description

technical field [0001] The present invention relates to a driving technology of a liquid crystal display device, and more particularly, to an apparatus and method for controlling the driving of a liquid crystal display device capable of recognizing occurrence of shutdown crosstalk noise when a liquid crystal panel is driven by a specific inversion method situation, and can switch to another inversion driving method in order to avoid this noise. Background technique [0002] With the recent development of IT (Information Technology), display devices play an important role as a medium for displaying visual information. In order to become the focus in the future, display devices need to satisfy conditions such as low power consumption, thin thickness, light weight, high image quality, and the like. [0003] The LCD device is a typical display device among flat panel display devices and displays images using optical anisotropy of liquid crystals. The LCD device has advantages ...
